Tiny, pink and quiet, with eyes closed ...
Xiwang was just 100 grams when I first saw her. Her birth brought much happiness to us. We named her Xiwang because it means "hope".
In the beginning, Xiwang couldn't see, hear or even move. We gave her round-the-clock
care. At six months old, she began to eat bamboo. Half a year later, she weighed over 35 kilograms. There is nothing more satisfying than seeing Xiwang grow into a big ball of fur.
When she was 20months old, she learnt to look after herself.
Xiwang has a happy life here. However, giant pandas in the wild face serious problems. They are very special animals. It is difficult for them to have babies. Even if baby pandas are born, they may easily get sick and die. Also, they live mainly on bamboo, but the bamboo forests are becoming smaller and smaller. As a result, pandas may not have a place to live or enough food to eat.
Luckily, the government has taken action. There are laws to protect giant pandas and more nature reserves for them to live in, Moreover, scientists are working hard to help pandas have more babies. Thanks to all the efforts, the number of giant pandas is increasing.

【详解】设化合物的化学式为AxBy或ByAx，元素A的相对原子质量为7M，元素B的相对原子质量为6M；化合物AxBy中A、B两元素的质量比=(7M×x):(6M×y)=7x:6y，根据题意：化合物中A、B两元素的质量比为7:15，则7x:6y=7:15，解得 x:y=2:5，则这种化合物的化学式为：A2B5或B5A2。
故选A。
